To all whom it may concern.-

Be it known that 1, CHARLES HQ' J. DILG, a citizen of the United States of America, and a resident of New York, in the county of New York and State of New York, have invented a certain new and useful Knife-Cleaning Machine, of which the following is a specification, the same being a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the art to which it appertains to make and use the same.

This invention relates to apparatuses for abrading or polishin purposes, and in articular to a machlne or cleaning and po ishing knives and like articles without any danger of inju to the blades or handles of the articles to e cleaned or polished or to the machine itself; and it has for. its object the roduction of a machine that will work satisactorily in the manner stated and which can be economically manufactured and which ma be easily and rapidly o. erated.

ith this object in view tfie invention consists in certain novel features of construction and combination and arrangement of arts, all of which will be hereinafter describe and specificallypointed out in the drawings, which accompany and form a part of this specification, and in which Figure 1 represents a side elevation of a machine constructed according to this invention. Fig. 2 is an end elevation of the same.

Fig. 3 is a side elevation of another embodiment of the invention. Fig. 4 is a plan view of the same. Figs. 5 and 6 are views in detail of the knife-rest. Fi 7 is a plan view, and Fig. 8'is a side elevatlon, of another machine constructed according to this invention. Fig. 9 is a side'elevation opposite to that of Fig. 8 and is taken on the line 9 9, Fig. 7 and Figs. 10, 11, 12, 13, and 14 are views in detail of the knife-guide.

Like letters of reference indicate like parts in all the views.

Referring articularly to the drawings, A denotes the rame of the machine, on which are mounted, on each side thereof, bell-crank lever's' B, pivoted at b, which levers serve to sup ort at the upper and free ends thereof sha ts C,each of which preferably carries a pa r of laterally-arranged cleaning-rolls C, wh ch latter ma be made of any suitable or desired materia and of any size preferred.

On each shaft C is mounted a gear-wheel a which meshes with one ear-wheel a of a air of intermeshing gear-w eels, one of whic is carried by the' driving-shaft a.

To the lower ends of the levers B are attached links I), the other ends of which links are pivoted together, as at b, and serve to sup ort a knife-rest rod D. This rod is prefera ly square in cross-section and is constructed and arranged ordinarily to work in a roller-guide, as between the rollers 11. At

the top of the rod (1 is mounted a narrow cushioned knife-rest D, the same being adjustably set upon the rod D by means of the set-screw d in order to be revolubly or vertically adjusted and having a cushion d narrow in width and convex in contour, extending approximately half-way around the top of the said kniferest, which cushion serves both to support the knife-blade and to form arr open space for the handle of the same in orderto prevent the latter from being worn ofi on the back and becoming thereby marred or abraded. U on the said knife-rest being depressed the r0 D will be pushed downward, and the action of lowerin the said knife-rest rod will cause the links to be s readout, thereby forcing the lower ends of t e levers B 9. art and causing the upper parts carrying t e cleaning-rolls to approach and the latter to contact each other.

Between each pair of cleaning-rolls a selfadjusting knife-guide is placed. This knifeguide (shown in detail in Fig. 13) consists of a bifurcated frame E, from the opposing ends of which hang swinging bars 6, to the lower ends of which is pivoted a cross-arm e, having bifurcated extremities e to straddle the frame E on each side. Two vertical guide-arms E rise from the center of the cross-arm 6, thus forming a slot, which is preferablylined with leather, fiber, or other suitable material, which is inserted in a recess formed in each of the opposite faces of the slot or recessed ortion, as at 6 Each of the guide-arms E has a bifurcated arm 6' to straddle one of the swinging bars e, and at the bottom of the slot a roller e is located, on which the back of the knife may rest. I made long enough to extend somewhat over the cleaning-rolls, as shown in Fig. 3, in order to prevent the knife-blade through the inad- Ordinarily the arms e are vertence of the operator from coming in contact with the upper portions of the cleaningrolls. This self-adjusting guide for the knifeeblade is held in its normal median position by gravity, andit will accommodate itself to any irregularity or variation in position or size of the cleaning-rollas, forexample, that said screw the rol s 0 ma be caused to ap-- proach toward or recede from the rolls 0 A driving-shaft a carries a 'gea'r wheel a, which meshes with a gear a, mounted on the frame or base-plate. The shafts of the gearwheel a, and the cleaning-rolls C are connected by means of a flexible or yielding shaft 0,. Y i 1 The machine just described is also furnished with a self-adjusting knife-guide like the one before described and accommodates V itself to the change of osition of the rolls C,

caused by the manipu ation of the screw 12.

If preferred, the, self-ad'usting knife-blade guide may be constructe and arranged as shown in Fig. 14, where the guide-arms E have rollers e which work in the frame E9, and also two rods e, which work in orifices in the sides of the said frame. In this case the self-adjusting knife-blade guide is held in its normal median position by means of opposit'ely-disposed springs e In the machine shown in Figs. 7, 8, and 9 a shaft a -is mounted on stationary posts rising from the base-plate A This shaft carries a cleaning-roll C and also preferabl has the same is placed a knife-rest D.

a bevel gear-Wheel a which meshes wit the bevel gear-Wheel a, of a manually-actuated shaft a. A shaft a has a swivel-bearing at one end of the same, consistin of a rod a, mounted in a post a. j The 0t er extremit of the shaft (1 is carried byone end of a bel crank lever B, the other end of which lever is raised and lowered from-the base A" b means of the adjusting-screw b. The shaft a carries a cleaning-roll C, and in front of Behind the plalllll-rdls is pivoted at e a self-adjustmg e-"blade guide E The. said guide 1s ke t in a normal median position by means of t e sprin -fingers which bear on opposite sides of t e guide against a post E o the base-plate A I. By means of the above construction the polishing-roll has not only a lateral or horizontal adjustment, but also a vertical one as well ,the latter being in the arc of a circle. I it is evident that many changes in the construction, form, proportion, and reiative arrangement of parts might be resorted to e spirit and scopewithout departin from t of my invention, would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such cha es' be substituted there or,

' aving jawsor. members, and means for sustaining the latter so as to move relatively lat:

erally and to hold the article to be treated in a relatively verticalposition during said lat eral movement and'to be moved by the said article to accommodate and adjust itself to any variation of the said roll. 2. In a machine of the character described, a polishing-roll, in combination with .a guide having jaws or members, and means forsustaining the latter so as to move relatively laterally and to hold the article'to be treated in a relatively vertical position during said lateral movement, the said jaws or members having .a slot or recessed portion formed in each of the op osite faces of the same.
